Hi


Thanks for using FixYa. From what you have described it seems that you have to replace the convergence IC and also check the power resistor, if values are not exact you have to replace them. These ICs are located behind the black heat sink; you can see once you open the back off the TV. Also, the convergence board should be checked for cracked solder joints and please make sure to check the resistors as if they are shot the ICs might blow again. All this is only recommended if you have electrical expertise and know how to solder/re-solder components, if not then you should get this done by a professional. The typical cost to get this fixed by a pro is around $300-$350. Please do accept the solution if the issue is resolved or else revert for further assistance.


Thanks
Rylee

Colors on tv are blurry, almost like when you watch a movie in 3-d, the red and green colors seem to go around the main image


This sounds like convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually $200-$400 Be sure to vote/rate me if this helped Thanks!

There is a picture but it is blurry with a big yellow blur.


Your TV most likely has one or more possible problems.

Problem #1: Convergence Chip Failure ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem
  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.



You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.


Problem #2 CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.

Samsung Rear Projection Problem (not convergence)


The tv has 2 focus adjustments for each tube, mechanical and electrical.

1. Mechanical focus is set by looking at screen from back (through inspection plate on back of most samsungs) and rotating the lens assembly on CRT. loosen wing nut and turn lens assembly to go through focus and back to best position.

Put convergence pattern on screen and manually misadjust bottom red and green lines convergence so they can be seen through inspection hole.

With back cover of TV off you can usually reach your hand up beside the lens assembly to loosen the wing nut then rotate to adjust. Green is in the middle. The focus will be obvious when you rotate and look

When you are finished make sure the foam dust protector is not over any of the lens assemblies and the wing nut is tight.

2. Electrical focus - located at front of unit. the front grille/speaker cover is removed and maybe a cover over the front crt inspection hole.

In the inspection hole there is a black plastic "Focus/screen adjust Assembly" with 2 rows of 3 controls.

One row is focus and the other is screen. The middle controls are for green with R/B on either side. Usually the controls are labelled as "focus" and "screen". You want to adjust the focus controls, one for each color. Look for the focus or screen label imprinted in the plastic. Don't play with the screen settings.

With the same misadjusted convergence pattern you can see a red, blue and green line. Adjust green focus and watch green line for best focus. Do same for other 2.

Screen adjustments are very exact and delicate. The easiest way to deal with them is to turn color off in Customer adjust menu. Put any color tone adjustments in the middle (low, med, high, put at med).

You should have a b/w picture if there are no crt or other color related faults. If it is close to B/W leave screens alone.

If the pix is too green, then the green screen setting must be reduced a small amount. Do not play with these adjustments as most TV repairrers have a difficult time adjusting them.

If focus adjustments don't help then focus control or CRT may be defective. Needs expert to determine.
